SEARCH FOR NONTHERMAL X-RAY EMISSION IN THE CLUSTER A1367

Observations of the rich nearby cluster A1367, with known extended intraclusterradio emission, are proposed with the XMM instruments. The proximity of A1367, and especially the low cluster gas temperature, make this cluster particularlysuitable for detection of nonthermal Xray emission at softest and hardest Xray energies of the EPIC detectors. Our simulations indicate that this emissionmay be measured by XMM with a 30 ksec observation. The scientific outputfrom such detection is quite important: in addition to the direct determination of the mean intracluster magnetic field and relativistic electron density, we will be able to gain important other insight on nonthermal phenomena truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
